Stapler cassette for packaging and dispensing staples in particular in an automatic frame assembling machine

ABSTRACT

A thin cassette provided with a plurality of passages separated by partitions and open outwards at the front orifices, and at a rear side. On the rear side, each passage is equipped with a driver resting against the staples contained therein.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a staple cassette adaptable in particular to anautomatic frame assembling machine.

2. Description of the Related Art

It is known that staples which are intended for fixing, betweenthemselves, the parts of a frame must have a profile and dimensionadapted to the mouldings used. For each of the categories or sizes ofstaples, the latter are, as they are manufactured, placed against eachother inside a loader which is in the form of an elongated receptacle.The role of this loader is thus not only to package a pack of staplesand make it easier to handle them, but also to serve as a dispenser inframe stapling machines. But, in high-speed automatic machines, theseloaders are clearly inadequate. Efforts are therefore being made toproduce dispensing magazines with a greater capacity, making it possibleto package a large number of staples and allowing them to beautomatically dispensed at a machine's stapling station.

SUMMARY OF THE INVENTION

The invention advantageously solves this problem by proposing a staplecassette serving as a packaging and dispensing means for an automaticstapling machine.

The object of the invention is thus a staple cassette for packaging anddispensing staples, in particular in an automatic frame assemblingmachine, which is thin and has a plurality of passages separated bypartitions, and open towards the outside at the front by means oforifices, as well as at the rear where each passage is provided with adriver resting against the staples contained therein.

Advantageously, grooves in the shape of the arc of a circle are formedby each orifice in the upper and lower curved panels of the cassette.

Additional characteristics, advantages and preferred methods of use ofthe cassette according to the invention will be better understood byreading the following description of an example in which reference ismade to annexed drawings representing:

DETAILED DESCRIPTION OF THE INVENTION

The staple cassette referred to as a whole by the reference 1 and shownin the figures in the general form of a flat case of slight thickness h.In the direction of its depth it has fifteen passages A, B, C . . . O,separated by partitions 2. At the rear side 3 of the cassette, thepassages are open to the outside. Each of them is provided with a driver4 resting against the staples contained in the corresponding passage.Moreover, each passage is edged, still at the rear side, with locators5, shown as notched portions in FIG. 2.

At the front side 6 of the cassette 1, the passages are also open to theoutside. Each orifice 7 forms, in the upper and lower curved panels ofthe cassette, a groove 8 in the shape of an arc of a circle, allowingthe passage to interact with the machine head. Through the orifices 7the ends of the staples 9 can be seen stored in the passages.

The drivers 4 hold the staples 9 in position pushed forward towards theside 6.

The cassette thus described, being thin, easily lends itself tostacking. Thus several superposed cassettes can be loaded in a magazinefeeding an automatic stapling machine. Each cassette is provided withidentical staples of the same height. On the other hand, it is possibleto stack cassettes provided with staples of different heights. It isthen up to the user to choose the cassettes on the basis of the type ofmoulding to be stapled. When a cassette is empty, the magazineautomatically loads a new one. The empty cassette is then pushed by thenew cassette until it falls into a receptacle provided for this purpose.

What is claimed:
 1. Staple cassette for packaging and dispensing staplesin particular in an automatic frame assembling machine, said staplesbeing placed against each other inside a loader which is in the form ofan elongated receptacle, characterized in that said cassette is thin andis provided with a plurality of passages in the direction of its depth,separated by partitions and open to the outside at the front sidethrough orifices and at the rear side and in that, at the rear side,each passage is provided with a driver resting against the staplescontained therein.
 2. Staple cassette according to claim 1 characterisedin that each passage is edged, at the front side of the cassette, withlocators.
 3. Staple cassette according to claim 1 characterised in thatgrooves in the shape of the arc of a circle are formed by each openingin the upper and lower curved panels of the box.
